Specification of Letters Patent.

Application mea my s, 1919. serial No. 295,974.

To all whom z't may concern:

Be it known that I, N ATHANIEL B. WALES, a citizen of the United States,residing at ew York. in the county of New York and State of New York,have invented certain new and useful Improvements in Closures forContainers, of which the following is a specification.

This invention relates to closure caps for bottles, jars, tubes orsimilar containers and its mainvobject is toprovide an effective sealingdevice which may be readily applied or removed by mere pressure of thefingers.

The closure is made of metal celluloid or other suitable material whichpossesses sufficient resiliency to permit of a certain amount ofdistortion so that it may be sprung out of normal shape to loosen thesecuring tongues, lips or lugs from the rim or flan e of the vessel orcontainer and will immedlately resumeV its shape when pressure isremoved.

I have illustrated the different forms of my invention in theaccompanying drawings, in which Figure 1 is a side elevation of a jar orbottle having my closure ap lied thereto; 1Fig. 2 is a slde elevation othe same turned at an angle of 90; Figs. 3 and 4 are vertical sectionalviews on the line A-A of Fig. 2 showing the closure in locked andunlocked positlons respectively; Figs. 5 and 6 are horizontal sectionalviews of the closure' in normal and distorted positions respectively;Figs. 7 and 8 are corresponding views of a. modified form of closure;Fig. 9 is a vertical sectional view of a jar or container showing aclosure of the type illustrated in Figs. 7 and 8 in unlocked ordistorted positlon; Fig. 10 is a fragmentary side elevation of a jarprovided with a screw top and showing my closure applied thereto; andFig. 11 is a plan view of the blank from which the closure is formed.

'My closure member or sealing cap is adapted for use upon bottles, jars,or tubular containers of any of the ordinary constructions in which theneck portion or to is provided with an annular fiange or ri or with anindentation, socket or recess to provide a ledge to receive the securingtongues or lips or gripping fingers of the closure ca I have slixown ajar 1, having an annular recess or groove providing a ledge 2 which maybe gripped by the tongues 5 of the closure caps 6.

The closure members are formed of metal or other suitable resilientmaterial and are' -,blank is then stamped into the form shown in Figs. 1and 2, in which the downwardly turned fiange is provided with areinforcing expanded annular bead or rib 8 below the slots 7 and fromwhich the tongues 5 depen'd and deflect inwardly.

The' function of the slots 7 upon opposite sides of the flange is tosever the rib portion 8 therebelow from the disk top part so that it mayfreely yield to lateral pressure. In the form illustrated in Figs'. 1 to6, the flange portion of the closure member is normally circular inoutline as indicated in Fig. 5. By pressing with the fingers against thesides of the ribs or beads 8 midway between the tongues 5, said sideswill move inwardly from the position indicated in broken lines in Fig. 6to that shown in full lines, the annular rib 8 becoming ovate insection. To accommodate `this movement the uncut end portion must bulgeoutwardly and as the part adjacent the flat disk cannot yield, thetongues 5 must rotate or swing outwardly, the lower free edges makingthe greatest movement. v

When the sides are pressed inwardly as indicated in Fig. 6, the tongues5 are separated sufiiciently to permit the cap to be sli ped over thetop of the jar or bottle as in icated in Fig. 4, and upon releasing thepressure the fiange will s normal shape indicated 1n Fig. 5. In thisposition, thetongues 5 take under the ledges 2 of the jar top and lockthe cap thereon. The parts may be so designed that the edges of the lipsor tongues will strike the up er inwardly inclined sides of ledges 2 sot at the resiliency of the metal will exert a. downward tendency andhold the ca tight upon the rim or mouth of the jar. For the purpose ofinsuring a more perfect seal, a gasket or packing washer 9 may beinterposed between the jar top and the inner side of the cap. Thiswasher may be constructed of cork or other suitable impervious materialand thus constitute an inner resilient sealing lining of the cap. Thisgasket or sealring back into the i ing disk may also serve to seal theslits 7 in the flange of the cap.

For certain purposes it may be desired to provide a greater range ofmovement of the clamping tongues and of the actuating elements of theflange 8. This may be accomplished by upsetting the metal slightly at.indicated in Fig. 8 in which the b-roken lines indicate the normalposition of the parts and the full lines the distorted or unlockedpositions. This construction necessarily increases the spring action ofthe clamp. The greater distance which the tongues will be moved is alsoindicated in Fig. 9, in which the tongues are in unlocked position.

ln Fig'. 10, I have shown the clamping tongues 5 obliquely arranged atsuch an angle that they will t over or mesh with and conform to thethreads of a jar havingl a screw top or neck. Other .changes andmodifications within the spirit of my inven- Vtion will readily appearto engineers and those who understand the principles of my closure capas above described. v

I claim 1. A closure cap for receptacles, comprising a disk having adepending flange provided with 'oppositely arranged clamping tongues,and the portions between the tongues beingl provided withcircumferentially extending slits.

Q. A closure cap for receptacles. comprising a fiat disk having adepending flange provided with a plurality of clamping tonguesdiametrically arranged, the intermediate portion of the flange beingspaced from the receptacleland yieldable, whereby the tongues will moveoutwardly in opposite directions when said intermediate Harige portionsare pressed inwardly.

3. A closure cap for receptacles, comprising a disk having a dependingflange provided with oppositely arranged clamping rtongues, and theportions between the tongues being provided with circumferentiallyextending slits, the part below the slits having an annular bead or ribformed therein.

In testimony whereof I affix my signature.

NATHANIEL B. WALES.
